如何使用亚马逊 MWS API 下载亚马逊报告

Question

我正在使用亚马逊报告 API 客户端库 - C# - 版本 2009-01-01，来自以下链接：Amazon Reports Client C#。

问题是，即使遵循该库中的示例，来自 MarketplaceWebServiceClient.cs 类的 GetReport(( 方法也不会在 GetReportResponse(( 响应中返回真正的报告。

那里似乎发生了一些事情，GetReportResponse 返回 NULL 而不是任何数据。

好的，经过几个小时的谷歌搜索，我想我找到了这个问题的答案。 如果您遵循亚马逊库样本，它们将永远不会得到正确的结果。

所以，我从这个网站上得到了正确的答案：下载-亚马逊-报告-using-mws-api

基本上，最重要的行是这些：

var request = new GetReportRequest();
//... (more details in a few)
var path = request.ReportId + "_" + Guid.NewGuid();
var thePath = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location) + "\" + string.Format("{0}.txt", path);
request.Report = File.Open(thePath, FileMode.OpenOrCreate, FileAccess.ReadWrite);  <-- this line makes the trick!

请求报告时，您需要打开一个文件并传递引用。 返回的报告文件将位于thePath.

这是我创建的测试方法，可用于检索报告。相应地更新您的 MWS API 凭据。您还需要从上面的链接下载亚马逊报告 API 库 C#。
